| 1 | Correlation between BRAF^(V600E) mutation and clinicopathological features in pediatric papillary thyroid carcinoma显示文摘In adults, the presence of the BRAF^(V600E) mutation in papillary thyroid cancer(PTC) has been demonstrated to be strongly associated with aggressive cancer-cell characteristics and poor patient prognosis. In contrast, the frequency of this mutation in pediatric PTC has undergone limited study, and the few available estimates range from 0 to 63%. Furthermore, the role of the BRAF^(V600E) mutation in pediatric PTC is controversial; thus, the present study aimed to investigate the prevalence and role of the BRAF^(V600E) mutation in48 pediatric patients with PTC, aged 3–13 years. Of these patients, 41 were diagnosed with classic PTC, five were found to have a follicular variant of PTC, and two to exhibit a diffuse sclerosing PTC variant. The BRAF^(V600E) mutation was identified to be present in 35.4% of the 48 analyzed patients, and in 41.5% of the patients diagnosed with classical PTC. Furthermore, the presence of the BRAF^(V600E) mutation was found to be associated with a patient age at diagnosis of less than ten years(P=0.011), the performance of a thyroidectomy(P=0.03), exhibited tumor multifocality(P=0.02) and/or extra-thyroidal invasion(P=0.003), and both a low MACIS(Metastases, Age, Completeness of resection, Invasion, Size)(P=0.036) and AMES(Age, Metastasis, Extent of tumor,Size)(P=0.001)score. Together, these data suggest that the presence of the BRAF^(V600E) mutation may be negatively correlated with partial aggressive clinicopathological features of pediatric PTC. | Jiangqiao Geng Huanmin Wang Yuanhu Liu Jun Tai Yaqiong Jin Jie Zhang Lejian He Libing Fu Hong Qin Yingluan Song Jinzhu Su Aiying Zhang Xin Wen Yongli Guo Xin Ni | 2017 | Science China(Life Sciences)2017，60，7： | 9 |
| 2 | DICER1 mutations in twelve Chinese patients with pleuropulmonary blastoma显示文摘Our aim is to examine the impact of DICER1 mutations on the pathogenesis of pleuropulmonary blastoma(PPB) by evaluating the mutation frequency and investigating the family history of Chinese patients with PPB. The family histories of 12 children with PPB recruited consecutively were surveyed. Blood samples from patients and their first-degree relatives were tested for DICER1 mutations. Whole-genome sequencing of blood samples and formalin-fixed and paraffin-embedded(FFPE) tumor tissue was performed in one family with twins. Twelve patients with PPB included six type II and six type III cases. Seven of the12 patients harbored DICER1 mutations, six of which were frameshift or nonsense mutations. Another case carried a germline DICER1 mutation affecting the splice site. FFPE sample had a nonsense mutation in TDG and missense mutations in DICER1.In addition, two cases with DICER1 mutations were found to have lung cysts preceding the diagnosis of PPB. Furthermore, one patient had a family history remarkable for thyroid diseases. Our results indicate that the germline mutation frequency in Chinese patients with PPB is similar to the ones reported for patients from USA, UK, and Japan. Moreover, our study strongly suggests that investigating the family history and detecting germline DICER1 mutations might be of benefit to increasing awareness and improving the accuracy of the differential diagnosis of PPB from non-malignant lung cysts. | Siyu Cai Xisi Wang Wen Zhao Libing Fu Xiaoli Ma Xiaoxia Peng | 2017 | Science China(Life Sciences)2017，60，7： | 5 |

| 4 | Overwhelming electrochemical oxygen reduction reaction of zinc-nitrogen-carbon from biomass resource chitosan via a facile carbon bath method显示文摘Developing high efficiency and low cost electrocatalysts is critical for the enhancement of oxygen reduction reaction(ORR),which is the fundamental for the development and commercialization of renewable energy conversion technology.Herein,zinc-nitrogen-carbon(Zn-N-C)was prepared by using biomass resource chitosan via a facile carbon bath method.The obtained Zn-N-C delivered a high specific surface area(794.7 cm^2/g)together with pore volume(0.49 cm^3/g).During the electrochemical evaluation of oxygen reduction reaction(ORR),Zn-N-C displayed high activity for ORR with an onset pote ntial E0=0.96 VRHE and a half wave potential E1/2=0.86 VRHE,which were more positive than those of the comme rcial 20 wt%Pt/C benchmark catalyst(E0=0.96 VRHE and E1/2=0.81 VRHE).In addition,the ZnN-C catalyst also had a better stability and methanol tolerance than those of the Pt/C catalyst. | Libing Hu Feng Yu Fu Wang Shengchao Yang Banghua Peng Long Chen Gang Wang Juan Hou Bin Dai Zhi-Qun Tian | 2020 | Chinese Chemical Letters2020，31，5： | 2 |
| 5 | High efficient oxygen reduction performance of Fe/Fe3C nanoparticles in situ encapsulated in nitrogen-doped carbon via a novel microwave-assisted carbon bath method显示文摘Fe-based carbon materials are widely considered promising to replace Pt/C as next-generation electrocatalysts towards oxygen reduction reaction (ORR). However, the preparation of Fe-based carbon materials is still carried out by conventional heating method (CHM). Herein, a novel microwave-assisted carbon bath method (MW-CBM) was proposed, which only took 35 min to synthesize Fe/Fe3C nanoparticles encapsulated in N-doped carbon layers derived from Prussian blue (PB). The catalyst contained large specific surface area and mesoporous structure, abundant Fe-Nx and C–N active sites, unique core-shell structure. Due to the synergistic effects of these features, the as-prepared Fe/Fe3C@NC-2 displayed outstanding ORR activity with onset potential of 0.98 VRHE and halfwave potential of 0.87 VRHE, which were more positive than 20 wt.% Pt/C (0.93 VRHE and 0.82 VRHE). Besides, Fe/Fe3C@NC-2 gave a better stability and methanol tolerance than Pt/C towards ORR in alkaline media, too. | Mincong Liu Xue Yin Xuhong Guo Libing Hu Huifang Yuan Gang Wang Fu Wang Long Chen Lili Zhang Feng Yu | 2019 | Nano Materials Science2019，1，2： | 1 |
| 6 | Pre-judgment and Incomplete Allocation Approach for Query Result Cache显示文摘Query result caching is a crucial technique employed in search engines, reducing the response time and load of the search engines. As search engines continuously update their indexes, the query results in long-lived cache entries may become stale. It is important to provide the refresh mechanism to enhance the degree of freshness of cached results. We present a pre-judgment approach to improve the freshness of the result cache and design an incomplete allocation algorithm. We introduce the queryTime-to-live(TTL) and term-TTL structure to pre-judge the result cache. The query-TTL is used to pre-check the likelihood of a cache hit and term-TTL is applied to maintain all terms of the latest posting list. For the cache structure, we design a Queue-Hash structure and develop the corresponding incomplete allocation algorithm. The preliminary results demonstrate that our approaches can improve the freshness of cached results and decrease processing overhead compared with no pre-judgment approaches. | QIAN Libing JI Zhenzhou FU Zhongchuan WU Qianqian SONG Guangjia | 2016 | Chinese Journal of Electronics2016，25，6： | 1 |

| 8 | Temperature distribution of fluids in a two-section two-phase closed thermosyphon wellbore显示文摘Compared with a conventional single section two-phase closed thermosyphon(TPCT) wellbore, a two-section TPCT wellbore has better heat transfer performance, which may improve the temperature distribution of fluid in wellbores, increase the temperature of fluid in wellheads and even more effectively reduce the failure rate of conventional TPCT wellbores. Heat transfer performance of two-section TPCT wellbores is affected by working medium, combination mode and oil flow rate. Different working media are introduced into the upper and lower TPCTs, which may achieve a better match between the working medium and the temperature field in the wellbores. Interdependence exists between the combination mode and the flow rate of the oil, which affects the heat transfer performance of a two-section TPCT wellbore. The experimental results show that a two-section TPCT wellbore, with equal upper and lower TPCTs respectively filled with Freon and methanol, has the best heat transfer performance when the oil flow rate is 200 L/h. | Zhang Yufeng Zhao Lun Fan Zifei Wu Xiaodong Fu Libing Xu Bifeng Kong Fanshun Jiang Shengdong | 2014 | Petroleum Science2014，11，2： | 0 |
| 9 | Inhibition of MALT1 paracaspase activity improves lesion recovery following spinal cord injury显示文摘Spinal cord injury(SCI) is a devastating traumatic injury that causes persistent, severe motor and sensory dysfunction. Immune responses are involved in functional recovery after SCI. Mucosa-associated lymphoid tissue lymphoma translocation 1(MALT1) has been shown to regulate the survival and differentiation of immune cells and to play a critical role in many diseases, but its function in lesion recovery after SCI remains unclear. In this paper, we generated KI(knock in) mice with a point mutation(C472 G) in the active center of MALT1 and found that the KI mice exhibited improved functional recovery after SCI.Fewer macrophages were recruited to the injury site in KI mice and these macrophages differentiated into anti-inflammatory macrophages. Moreover, macrophages from KI mice exhibited reduced phosphorylation of p65, which in turn resulted in decreased SOCS3 expression and increased pSTAT6 levels.Similar results were obtained upon inhibition of MALT1 paracaspase with the small molecule inhibitor‘‘MI-2' or the more specific inhibitor ‘‘MLT-827'. In patients with SCI, peripheral blood mononuclear cells(PBMC) displayed increased MALT1 paracaspase. Human macrophages showed reduced proinflammatory and increased anti-inflammatory characteristics following the inhibition of MALT1 paracaspase. These findings suggest that inhibition of MALT1 paracaspase activity in the clinic may improve lesion recovery in subjects with SCI. | Hua Zhang Guodong Sun Xiaowei Li Zhen Fu Chengbin Guo Guangchao Cao Baocheng Wang Qian Wang Shuxian Yang Dehai Li Xichun Xia Peng Li Jing Zhu Wei Zhou Liangyan Zheng Jingxia Li Lei Zhang Jianlei Hao Libing Zhou Frederic Bornancin Zhizhong Li Zhinan Yin Yunfei Gao | 2019 | Science Bulletin2019，64，16： | 0 |
| 10 | Hepatoblastoma with neonatal necrotizing enterocolitis:Two case reports显示文摘We report two children with hepatoblastoma(HB)with a history of neonatal necrotizing enterocolitis(NEC).Case 1 was diagnosed with HB at 5 months of age.Liver enlargement was found during the NEC operation at 3 months of age and then was clinically diagnosed by imaging.After six chemotherapy courses,a partial hepatectomy was performed.Three months after ceasing the chemotherapy,a chest computed tomography scan suggested that distant metastasis of the tumor should be considered,and the lesion was removed.However,9 months after the operation,alpha-fetoprotein concentrations were increased,and abdominal imaging showed a recurrence of the tumor in situ,resulting in a hepatectomy.Case 2 was diagnosed with NEC shortly after birth and underwent an intestinal resection and anastomosis 1 month later.He was diagnosed with HB at 3 years of age.Hepatectomy was performed after five courses of chemotherapy.Chemotherapy was stopped after 10 courses,and alpha-fetoprotein concentrations were normal.At present,both children have survived and are in a healthy condition.Physicians should be aware of the possibility of HB and a history of NEC in children.Premature birth and low birth weight are common factors leading to the pathogenesis of HB and NEC.The association between these two diseases requires further study。 | Sidou He Xisi Wang Chao Duan Wen Zhao Chiyi Jiang Shihan Zhang Binglin Jian Wei Yang Tong Yu Libing Fu Huanmin Wang Xiaoli Ma | 2023 | Cancer Innovation2023，2，6： | 0 |

| 12 | Identification of Germline Mutations in East‑Asian Young Never‑Smokers with Lung Adenocarcinoma by Whole‑Exome Sequencing显示文摘Recently,an increasing number of young never-smokers are diagnosed with lung cancer.The aim of this study is to investigate the genetic predisposition of lung cancer in these patients and discover candidate pathogenic variants for lung adenocarcinoma in young never-smokers.Peripheral blood was collected from 123 never-smoking east-Asian patients diagnosed with lung adenocarcinoma before the age of 40.Whole-exome sequencing(WES)was conducted on genomic DNA extracted from peripheral blood cells.As a result,3,481 single nucleotide variants were identified.By bioinformatical tools and the published gene list associated with genetic predisposition of cancer,pathogenic variants were detected in ten germline genes:ATR,FANCD2,FANCE,GATA2,HFE,MSH2,PDGFRA,PMS2,SDHB,and WAS.Patients with pathogenic variants were more likely to occur in females(9/10,90.0%)and have stage IV lung adenocarcinoma(4/10,40%).Furthermore,germline muta-tions in 17 genes(ASB18,B3GALT5,CLEC4F,COL6A6,CYP4B1,C6orf132,EXO1,GATA4,HCK,KCP,NPHP4,PIGX,PPIL2,PPP1R3G,RRBP1,SALL4,and TTC28),which occurred in at least two patients,displayed potentially pathogenic effects.Gene ontology analysis further showed that these genes with germline mutations were mainly located in nucleo-plasm and associated with DNA repair-related biological processes.The study provides spectrum of pathogenic variants and functional explanation for genetic predisposition of lung adenocarcinoma in young never-smokers,which sheds a light on prevention and early diagnosis of lung cancer. | Fangqiu Fu Xiaoting Tao Zhonglin Jiang Zhendong Gao Yue Zhao Yuan Li Hong Hu Libing Shen Yihua Sun Yang Zhang | 2023 | Phenomics2023，3，2： | 0 |
| 13 | Motor neuron-specific RhoA knockout delays degeneration and promotes regeneration of dendrites in spinal ventral horn after brachial plexus injury显示文摘Dendrites play irreplaceable roles in the nerve conduction pathway and are vulnerable to various insults.Peripheral axotomy of motor neurons results in the retraction of dendritic arbors,and the dendritic arbor can be re-expanded when reinnervation is allowed.RhoA is a target that regulates the cytoskeleton and promotes neuronal survival and axon regeneration.However,the role of RhoA in dendrite degeneration and regeneration is unknown.In this study,we explored the potential role of RhoA in dendrites.A line of motor neuronal conditional knockout mice was developed by crossbreeding HB9~(Cre+)mice with RhoA~(flox/flox)mice.We established two models for assaying dendrite degeneration and regeneration,in which the brachial plexus was transection or crush injured,respectively.We found that at 28 days after brachial plexus transection,the density,complexity,and structural integrity of dendrites in the ventral horn of the spinal cord of RhoA conditional knockout mice were slightly decreased compared with that in Cre mice.Dendrites underwent degeneration at 7 and 14 days after brachial plexus transection and recovered at 28–56 days.The density,complexity,and structural integrity of dendrites in the ventral horn of the spinal cord of RhoA conditional knockout mice recovered compared with results in Cre mice.These findings suggest that RhoA knockout in motor neurons attenuates dendrite degeneration and promotes dendrite regeneration after peripheral nerve injury. | Mi Li Jiawei Xu Ying Zou Jialing Lu Aiyue Ou Xinrui Ma Jiaqi Zhang Yizhou Xu Lanya Fu Jingmin Liu Xianghai Wang Libing Zhou Jiasong Guo | 2023 | Neural Regeneration Research2023，18，12： | 0 |
| 14 | Detection of FOXO1 break-apart status by fluorescence in situ hybridization in atypical alveolar rhabdomyosarcoma显示文摘The morphologies of alveolar rhabdomyosarcoma(ARMS) are various. Some cases entirely lack an alveolar pattern and instead display a histological pattern that overlaps with embryonal rhabdomyosarcoma(ERMS). The method of pathological diagnosis of ARMS and ERMS has been updated in the 4th edition of the World Health Organization's guidelines for classification of skeletal muscle tumors. Under the new guidelines, there is still no molecular test to distinguish between these two subtypes of rhabdomyosarcoma(RMS). In the present study, we applied fluorescent in situ hybridization(FISH) and found that the Forkhead box O1(FOXO1) gene broke apart, amplified, and displayed an aneuploid signal that was related to the RMS pathological subtype.Aside from the fact that FOXO1 break-apart and its amplification were correlated with atypical ARMS, aneuploidies were usually found in atypical ERMS. In conclusion, our results detail a potential biomarker to improve the accuracy of pathological diagnosis by discriminating between atypical ARMS and atypical ERMS. | Libing Fu Yaqiong Jin Chao Jia Jie Zhang Jun Tai Hongbin Li Feng Chen Jin Shi Yongli Guo Xin Ni Lejian He | 2017 | Science China(Life Sciences)2017，60，7： | 0 |
